i DRIVING MECHANISM FOR GINS.

SPECIFICATION forming part of Letters Patent No. 634,800, dated October 10, 1899. Application iiled J'nly 20, 1899. Serial No. 724,456. I (No model.)

To LLZZ whom, it may concern:

Be it known that I, COLBERT4 IV. BROWN, of Leonard, in the county of Fannin and State of Texas, have invented a new and Improved Driving Mechanism for Gins, of which the following is a full, clear, and exact description.

This invention relates to improvements in driving mechanisms for the brush and saws of cotton-gine or the like; and the objectv is to provide a simple mechanism whereby the brush is driven practically by the same belt that drives the saws and whereby the motionV of the machine will be regular and even.

I will describe a driving mechanism for gins embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the gures.

Figure 1 is a partial section and partial elevation of a driving mechanism embodying my invention, and Fig. 2 is an elevation of aportion of the driving mechanism.`

Referring to the drawings, 1 designates the,

gin-casing, arranged on the usual table or platform 2 and having within it the usual saws 3 and the brush 4. A band-wheel 5 is secured to the saw-shaft and is driven by a band 6, leading from lthe power-wheel 7. Mounted on the shaft of the brush 4 is a pulley 8, from which a band 9extends to a pulley 10, having its shaft-bearings in a bifurcated arm 11, and at the outer end is pivot-l ally-connected to the lowerend ofk a bar 12, mounted to swing on the casing 1.

Extended forward from the bar 12 is a shifting rod 13, provided with teeth 14, either one of which may be engaged with a plate 15, secured to ,thecasing 1. A spring 16 is con nected at one end to the army 11 --and at the other' end to a screw 17, movable through a stud 18 and provided above said stud with an'adjusting-nut 19. This spring is designed to hold the pulley 10 or the band 9, running around the same, in yielding connection with the band 6, and the tension of the spring may be adjusted by means of the screw-rod 17 and thenut 19. t

In operation While the power-wheel 7 is in motion the pulley 10 is to be drawn toward the belt 6 by means of the rod 13, which is to be held in its adjusted position by means of the plate 15 engaging with one of the teeth 14. When the parts are in this position, the belt 6 will be tightened, so as to impart motion to the band-Wheel 5, and the movement band bein'g loose, a pulley on the brush-cylinder shaft, a swinging arm, a pulley on said arm, a band extended from said pulley to the pulley on the brush-cylinder shaft, a spring for holding the arm yieldingly toward the first-named band, and meansfor moving said arm toward and from the first-named band, substantially as specified.

2. A driving mechanism forgins, comprising a power-Wheel, a saw-shaft, a band-Wheel on the saw-shaft, a loose band connecting said two wheels, a brush-cylinder shaft, a bar hav-v ing swinging connection with the gin frame or casing, an arm pivotally connected to the bar, a pulley mounted o n said arm, a band connection between said pulley and a pulley on the brush-cylinder sha-ft, a spring connected at one end of said arm, an adjusting- Vrod to which the other end of the spring is attached, a toothed shifting rod extended from the bar, and a detent for engaging` with a tooth on theV shifting rod, substantially as specified.
